Entering new messages very wretched

This forum message entry form is buggy. When changing row (enter), cursor often jumps up instead down. Or when typing message, you may find next word starting in wharever row, without any reason. It may be impossible to insert cursor and start typing in the message end - while clicking in the end cursor starts blinking there but when starting typing jumps instantly to the very beginning.
When clicking to post message, one may end himself repeatedly on empty entry form with text “An Unexpected error has occuurred” … required to type all your message over again and again.


 I have experienced these problems on different computers not only on my own.
Therefore I have started to prepare message on notepad and use copy paste here.
With hoping that NIS2009 might be more reliable.
